Current projects

Our research examines the selective binding and transport of ions, water and other small molecules through porous structures. A particular focus is the family of ion channel proteins that regulate electrical signalling in organisms by providing selective pathways for ions across cell membranes that can be opened and closed in response to various stimuli. Gaining a fundamental understanding of these proteins at an atomic level may aid the treatment of a range of neuromuscular diseases from epilepsy to muscular dystrophy. Selective binding and transport is also a feature of many synthetic molecules that are finding applications in a range of industries.

Proteins and macromolecules can be difficult to study due to their size, functioning at the interface of microscopic molecular behaviour and macroscopic mechanical behaviour. To investigate them we use a combination of computational techniques including ab initio, molecular dynamics, coarse grain, Brownian dynamics and macroscopic calculations. In addition we utilise FRET microscopy (Förster Resonance Energy Transfer) to experimentally study the conformational changes of proteins as they function.

Research Highlight: Cheaper fresh water from desalination

Many parts of the world, including most of Australia’s major cities are facing water shortages due to both an increasing population and shifts in the climate. Desalination of sea water via reverse osmosis is an attractive means of obtaining potable water, but one of its main drawbacks is the energy and cost required to force the water through semipermeable membranes that block the passage of the salt. The energy costs could be reduced, however, if new membranes could be developed with continuous pores that offer less resistance to water. Many narrow biological pores do just this: a pore of a given radius surrounded by non-polar atoms can allow for water to pass, but impede the passage of ions. Research in the group has shown that membranes formed from synthetic pores that mimic these biological channels, such as carbon nanotubes, can be used in desalination. Not only has this work shown the exact dimensions of the pores that are required, but also that such membranes could significantly reduce the energy cost of reverse osmosis.
